I recently changed from using vim on a linux-based system to OS X, and am having trouble with some of the keybindings. Note that i am not using macvim, just the regular command line vim. i have tried this in both Terminal.app and iTerm2.app with the same results:
The keybindings for moving forward or back a word, (w, e, b, etc.) don't work. the result of pressing any of these keys in normal mode is just a terminal bell. i also have a couple of mappings in my vimrc file, to switch between tabs using M-right and M-left, neither of which function any longer.
my left option key is set to act as meta/Esc+. in bash, left-option-key indeed functions correctly and i can jump around by word (using bash shortcuts). so this seems to be limited to vim.
i have googled around and it doesn't seem like others have this problem. i wondered if it might be an error in my vimrc file, but since even the built-in w, e, b etc. movements don't work, that doesn't seem to be it. this question looks similar, but is unanswered. i find it hard to believe that everyone who uses os x and vim doesn't use any of these bindings? maybe everyone just uses macvim?
TIA for any advice!
